CAR-COUPLING.

Specification of Letters Patent.

Patented Nov. 30, 1915.

` Application filed August 9, 1913. Serial No. 783,930.

subject of the King of Great Britain, and a resident of Derby, county of Derby, England, have invented new and 'useful Improvements in Car-Couplings, of which the following is a specification, referencefbeing had to the accompanying drawings, in which- Figure 1 is a horizontal section of my improved coupler, showing the parts in ylocked position; Fig. 2 is a horizontal section showing the parts in opened position; Fig. 3 is a section on lines III-III of Fig. 1; Fig. 4 is a similar section showing the lock in lock-set position; Fig. 5 is a similar section showing the manner in which the lock is lifted into lock-set position; Fig. '6 is a section on lines VI-VI of Fig. 2 showing the parts in knuckle opening position; Figs. 7, 8 and 9 are details of the look; Fig. 10 is a detail of the lifter, and Fig. 11 is a detail of the opener.

My invention relates to car couplers and is comprised of improvements on the type of car couplers described and claimed in my co-pending application filed February 6, 1913, Serial No. 746,559.

My improvements relate especially to the manner and means for operating the locking block and the parts cooperating therewith.

Referring to the drawings, A is the Vcoupler-head, B is the knuckle, C is the lock, D the lock lifter, and E the knuckle opener. The lock C has on its under side a bevel face 2, with which the beveled face 3 on the vertically extending arm 4 of the lifter D is adapted to be move-d into engagement as it is raised from its lower and noperativeposition, as is shown in Fig. 3, by a pull applied to itslower end. As soon as the lower edge 6 of the lock C is raised by the lifter D to a position just above the level of the lock-set ledge 7, in which position the knuckle B is unlocked and free to open, the lock tilts under gravity until its edge 6 rests on the ledge 7, as is shown in Figs. 4 and 5. At the same time a second arm 8 on the lifter D is brought into engagement with the under side 9 of the opener E and with its depending projection 10, s0 that the lifter D is prevented from rising higher. The point of engagement of the arm 8 with the under side 9 of the opener E becomes a floating fulcrum` in the vertical direction for the lifter D while the lateral project-ions or trunnions 11 on the lifter ooacting with the vertically extending grooves 12 on the under side of the coupler head serve to guide it in its upward movement7 and act as pivots for movement in a lateral direction. The lifter D, as it turns on the projections 11, will engage the depending projection 10 and cause the opener E to move transversely on the fulcrum 13 of its rearwardly extending portion 14, which is located in the shank 15 of the coupler, while the part 4 of the lifter D will swing below the lock into the recess 16 of the coupler head, as in Fig. 6. The web 17 on the lifter Dy coperates with the grooves 12 to maintain the lifter in vertical position while it is in lowermost position, but while the lifter is being raised vertically to lift the lock, it is retained in vertical position by reason of its part 4 engaging the surface 27 of the coupler A, until part 4 clears the edge 27a, whereupon the lifter becomes free to turn on its trunnions 11.

The lateral movement of the opener E will cause the knuckle to open by reason of the "coperation of the pin 18 of the opener therewith. The fulcrum 13 upon the rear end of opener E is comprised of two vertically-disposed arms 19. which prevent vertical movement of the opener, while lateral resistance is aiforded by a side wall of the coupler shank and by the abutments 20.

In the knuckle opening movement, as the opener E turns about its pivot, its projec tion 21 is brought into Contact with the inclined face 21EL of the lock and lifts the lock positively ofi' of the lock-set ledge 7, which is formed on the wall of the coupler cavity on the guard-arm side and is arranged substantially parallel to the line of draft.

During the closing movement of the knuckle, the opener E in moving back carries the lock C, then resting upon it, away from the ledge 7, so that the lock, as soon as the opener E has passed from beneath it, becomes free to fall verticallyinto its locking position in front of the knuckle tail and with its two locking surfaces 22 and 23 in contact with the coperating faces 24 and 25 on the side and front of the coupler cavity respectively.

For the purpose of permitting the knuckle to be moved from partially opened to full opened position by the lifting lever, the depending projection on opener 4E is provided with an inclined under face 26 with which the correspondingly inclined face 3 of the lifter D engages, and by reason ofthe engagement of these two faces 26 and 3 the opener E will, as the lifter D without turning on its trunnions 1l is raised still farther in a vertical direction, move the opener and the knuckle into full open position, as is shown in dotted lines in Fig. 4f.

Various modifications may be made in the device which I have shown and described herein without departing from my invention.

Iaving now described the nature of my said invention and the best means I know of carrying the same into practical effect, I claim l. In a car coupler having a lock, a knuckle and a knuckle opener, a lifter having a bifurcated jaw, and guiding means on the coupler head` coperating with the lifter to give it an initial vertical movement, one of said bifurcations coperating with the lock to lift it, and the other of said bifurcations being adapted to actuate the knuckle opener to dislodge the lock from lock-set position.

2. In a car coupler having a lock, a

" knuckle and a knuckle opener, a lifter having a bifurcated jaw, guiding means on the coupler head cooperating with the lifter to give it an initial vertical movement, and trunnions on the lifter upon which the lifter is adapted to pivot after the initial lifting has been completed, one of said bifurcations coperating with the lock by a direct vertical movement and the other of said bifurcations coperating with the opener to actuate it to throw the knuckle by a rotary movement.

3. In a car coupler having a lock, a knuckle, a knuckle opener and a lock lifter, said lifter having two arms, one of said arms being adapted to cooperate with the opener in one position to open the knuckle, and the other of said arms being adapted to actuate the opener when in another position to open the knuckle.

el. In a car coupler having a lock, a knuckle and a knuckle opener, alock lifter having an extending arm, the said arm being adapted in one position to lift the lock to open position and in another position to actuate the knuckle opener to trip the lock off the lock-set seat and open the knuckle.

5. In a car coupler having a lock, a knuckle, a knuckle-opener, and a lock lifter, said lifter being adapted by a rotary movement to actuate the opener to throw the knuckle open from closed position, and by a direct vertical movement to actuate the opener to throw the knuckle open from halfopened position.
